Hands-free mode

Why we like it: Microsoft is introducing gesture control features in Windows 8.1 with the new Food and Drink app. To avoid touching the screen with filthy hands while cooking, you can wave your hand by the camera to move from page to page. It still doesn't feel completely polished, but it's a very useful feature.

How to use it: Tap the button that says "Hands-Free Mode" at the bottom of any recipe and wave the palm area of your hand left or right past your webcam to move backwards and forwards.
